libpng2 and libpng3

[Shaun Jackman <sjackman@shaw.ca>]

I upped my KDE version to the latest -tunstable. Along with this apt 
installed libpng3. Now I'm having some trouble with certain KDE apps not 
being able to find their icons.

example... 
$ korganizer
libpng warning: Application was compiled with png.h from libpng-1.2.1
libpng warning: Application  is running with png.c from libpng-1.0.12
libpng error: Incompatible libpng version in application and library
[clip]

For some reason korganizer links to both libpng2 and libpng3. I'm not quite 
sure why this is, but I thought it might be useful.
$ ldd /usr/bin/korganizer | grep png
        libpng.so.2 => /usr/lib/libpng.so.2 (0x40d05000)
        libpng.so.3 => /usr/lib/libpng.so.3 (0x41061000)

Its kicker icon doesn't load either.

Versions...
ii  libpng2        1.0.12-3       PNG library - runtime
ii  libpng3        1.2.1-1        PNG library - runtime
ii  korganizer     2.2.2-4        Personal organizer based on Qt and KDE
ii  kdelibs3       2.2.2-10       KDE core libraries (runtime files)
